quasi-orthogonal 解釋
準正交的
  • quasi : adv 1 在某一意義上，有點，幾乎。2 恰如，宛如，就像是。3 就是說，即〈略作 q 或 qu 尤用以作語源上的...
  • orthogonal : adj. 1. 直角的，互相垂直的；正交的；直交的。2. （統計數字）互不相關的。
  1. Then based on the analysis of the constructions of wh, go and ls sequences, the corresponding correlation properties are derived and methods of selecting subsets with good periodic mean - square cross - correlation property or aperiodic mean - square correlation property from the wh set and go sequence set whose go zone z = l are investigated. furthermore, the methods of truncating the go sequences to obtain the quasi - orthogonal ( qo ) set whose family size m is larger than the length l and the quasi - generalized - orthogonal ( qgo ) set whose size m is larger than li2z are discussed, together with the numerical results of the correlation properties

    基於這些結果，探討了如何從wh序列集和廣義正交區z = 1的go序列集中，分別按照周期互相關均方特性最優和非周期相關均方特性最優的準則選擇性能較好的序列子集；同時討論了將廣義正交序列截短來獲得準正交（ qo ）序列集和廣義準正交序列集（ gqo ）的方法，並給出了這一類序列相關特性的數值計算結果。
